The Worm Moon Cut

The best days to cut your hair for growth in March 2027 are Thursday the 18th and Friday the 19th, while the moon is waxing through Leo. If you would rather the shape held, cut between the 23rd and the 26th, once the moon has passed full.

March 2027 gives you something February did not. Two complete days in the growth window instead of one, and both fall on a Thursday and a Friday. The lunar hair calendar for March 2027 is unusually kind if you are willing to book ahead.

Every moon phase in March 2027, with exact times

All four phases, calculated rather than remembered. Times are given in US Eastern and Pacific, with UTC for everyone else. Watch the clocks this month: they go forward in the United States on Sunday 14 March, so the first phase is on standard time and the rest are not.

• New Moon in Pisces: Monday 8 March, 4:29 AM ET, 1:29 AM PT, 09:29 UTC
• First Quarter in Gemini: Monday 15 March, 12:25 PM ET, 9:25 AM PT, 16:25 UTC
• Full Worm Moon in Libra: Monday 22 March, 6:43 AM ET, 3:43 AM PT, 10:43 UTC
• Last Quarter in Capricorn: Monday 29 March, 8:53 PM ET, 5:53 PM PT, which is Tuesday 30 March at 00:53 UTC

Every phase this month lands on a Monday, which happens because the lunar cycle sits close to four exact weeks, and means nothing more than that. The next new moon falls on 6 April at 7:51 PM ET. For the wider view we keep every new moon and full moon date out to 2028 in one place.

Best days to cut your hair for growth in March 2027

Thursday 18 and Friday 19 March. Two conditions have to line up. The moon has to be waxing, which is the stretch between the new moon on the 8th and the full moon on the 22nd, and it has to be passing through a sign the tradition ties to hair, which is Leo for length and volume.

The moon enters Leo late on Wednesday 17 March at 11:40 PM ET and leaves in the small hours of Saturday the 20th at 1:37 AM ET, which gives you two complete days inside the overlap rather than the single day February offered. On the West Coast it opens earlier, at 8:40 PM PT on the 17th, so a late Wednesday appointment counts there too.

If neither day works, the whole waxing half is still useful for length. Anything from the 9th to the 21st sits inside it, and last month's February 2027 calendar is still up if you are planning two cuts ahead.

Best days for thickness and strong roots

Thursday 11, Friday 12 and Saturday 13 March. The moon is in Taurus across those days and still waxing, and Taurus is the earth sign the tradition ties to density and root strength rather than speed.

The moon enters Taurus at 11:16 AM ET on the 11th and leaves at 4:30 PM ET on the 13th, so Friday the 12th is the only complete day in the window, with Thursday afternoon and Saturday morning as the edges. This is the earlier of the two options this month, and it comes before the clocks change.

Best days to cut if you want the shape to stay

23 to 26 March. Once the moon has passed full it begins to wane, and the tradition reverses. A waning cut is said to slow regrowth, which is what you want for a fringe you are tired of trimming, or for any cut you are paying properly for and would like to keep.

Within that stretch, Tuesday the 23rd has the moon in Libra, which tradition associates with shape and balance, and it is the one complete waning day in that sign. The 25th and 26th sit in Scorpio, the more structural end of the same idea.

Avoid a big change on the 8th. The new moon is traditionally a day for starting nothing, and the same applies to the 22nd once the full moon has peaked.

What the Worm Moon in Libra is adding

March's full moon has carried the name Worm Moon for a long time, drawn from North American almanac tradition. The usual explanation is earthworms returning to softening ground, though some accounts trace it to the beetle larvae that appear as bark thaws. Either way the meaning holds, which is the season when something buried starts moving again.

This year it arrives in Libra, two days after the equinox. The sun crosses into Aries on Saturday 20 March at 4:21 PM ET, so the Worm Moon is the first full moon of the new astrological year. A Libra full moon is not asking you to overhaul anything. It is asking what is out of proportion, which is a more useful question to bring to a mirror than most of the ones we bring.

If you want a practice rather than only a haircut, the weekly hair growth ritual is the place to start.

An honest note before you book

None of this is proven. There is no good evidence that the phase of the moon changes how fast hair grows, and we have written that plainly in does the moon affect hair growth rather than leaving it out of a calendar we publish every month.

What the calendar reliably gives you is a date. Hair responds to being trimmed on a schedule far more than to anything else, and most people do not keep a schedule without a reason to. The moon is a very old reason, it is free, and it arrives whether or not you were paying attention.

If you follow the Chinese almanac instead, the feng shui haircut calendar runs on lunar months rather than moon phases, so the two will not agree. We keep them separate on purpose.

Common questions about the lunar hair calendar for March 2027

What are the best days to cut hair in March 2027? The 18th and 19th for growth, while the moon is waxing in Leo. The 11th to 13th for thickness, while it is waxing in Taurus. The 23rd to 26th if you want the cut to hold its shape, once the moon is waning.

When is the full moon in March 2027? Monday 22 March at 6:43 AM ET, 3:43 AM PT, 10:43 UTC. It is the Worm Moon, and it falls in Libra.

When is the new moon in March 2027? Monday 8 March at 4:29 AM ET, 1:29 AM PT, 09:29 UTC, in Pisces.

Should you cut your hair on a waxing or waning moon? Waxing if you want it to grow back quickly and fuller, which in March 2027 means the 9th to the 21st. Waning if you want it to grow back slowly and keep its shape, which means the 23rd onward. This is tradition, not a proven effect.

Is it bad to cut your hair on the full moon? Tradition treats the exact day of the full moon as a peak to work up to rather than cut on, and suggests the day or two before instead. In March 2027 that points at the 18th and 19th rather than the 22nd.

The calendar is not the point. Keeping the appointment is the point.
